    \class QUrl

    \brief The QUrl class provides a convenient interface for working
    with URLs.

    \reentrant
    \ingroup io
    \ingroup misc
    \ingroup shared
    \mainclass

    It can parse and construct URLs in both encoded and unencoded
    form. QUrl also has support for internationalized domain names
    (IDNs).

    The most common way to use QUrl is to initialize it via the
    constructor by passing a QString. Otherwise, setUrl() and
    setEncodedUrl() can also be used.

    URLs can be represented in two forms: encoded or unencoded. The
    unencoded representation is suitable for showing to users, but
    the encoded representation is typically what you would send to
    a web server. For example, the unencoded URL
    "http://b\uuml\c{}hler.example.com" would be sent to the server as
    "http://xn--bhler-kva.example.com/List%20of%20applicants.xml".

    A URL can also be constructed piece by piece by calling
    setScheme(), setUserName(), setPassword(), setHost(), setPort(),
    setPath(), setEncodedQuery() and setFragment(). Some convenience
    functions are also available: setAuthority() sets the user name,
    password, host and port. setUserInfo() sets the user name and
    password at once.

    Call isValid() to check if the URL is valid. This can be done at
    any point during the constructing of a URL.

    Constructing a query is particularly convenient through the use
    of setQueryItems(), addQueryItem() and removeQueryItem(). Use
    setQueryDelimiters() to customize the delimiters used for
    generating the query string.

    For the convenience of generating encoded URL strings or query
    strings, there are two static functions called
    fromPercentEncoding() and toPercentEncoding() which deal with
    percent encoding and decoding of QStrings.

    Calling isRelative() will tell whether or not the URL is
    relative. A relative URL can be resolved by passing it as argument
    to resolved(), which returns an absolute URL. isParentOf() is used
    for determining whether one URL is a parent of another.

    fromLocalFile() constructs a QUrl by parsing a local
    file path. toLocalFile() converts a URL to a local file path.

    The human readable representation of the URL is fetched with
    toString(). This representation is appropriate for displaying a
    URL to a user in unencoded form. The encoded form however, as
    returned by toEncoded(), is for internal use, passing to web
    servers, mail clients and so on.

    QUrl conforms to the URI specification from
    \l{RFC 3986} (Uniform Resource Identifier: Generic Syntax), and includes scheme extensions from
    \l{RFC 1738} (Uniform Resource Locators).

    \sa QUrlInfo
*/

/*!
    \enum QUrl::ParsingMode

    The parsing mode controls the way QUrl parses strings.

    \value TolerantMode QUrl will try to correct some common errors in URLs.
                        This mode is useful when processing URLs entered by
                        users.

    \value StrictMode Only valid URLs are accepted. This mode is useful for
                      general URL validation.

    In TolerantMode, the parser corrects the following invalid input:

    \list

    \o Spaces and "%20": If an encoded URL contains a space, this will be
    replaced with "%20". If a decoded URL contains "%20", this will be
    replaced with a single space before the URL is parsed.

    \o Single "%" characters: Any occurrences of a percent character "%" not
    followed by exactly two hexadecimal characters (e.g., "13% coverage.html")
    will be replaced by "%25".

    \o Non-US-ASCII characters: An encoded URL should only contain US-ASCII
    characters. In TolerantMode, characters outside this range are
    automatically percent-encoded.

    \o Any occurrence of "[" and "]" following the host part of the
    URL is percent-encoded.

    \endlist
*/

/*!
    \enum QUrl::FormattingOption

    The formatting options define how the URL is formatted when written out
    as text.

    \value None          The URL is left unchanged.
    \value RemoveScheme  The scheme is removed from the URL.
    \value RemovePassword  Any password in the URL is removed.
    \value RemoveUserInfo  Any user information in the URL is removed.
    \value RemovePort      Any specified port is removed from the URL.
    \value RemoveAuthority
    \value RemovePath   The URL's path is removed, leaving only the scheme,
                        host address, and port (if present).
    \value RemoveQuery  The query part of the URL (following a '?' character)
                        is removed.
    \value RemoveFragment
    \value StripTrailingSlash  The trailing slash is removed if one is present.
